説明する。The present invention provides an electrical laminate, characterized in that it is formed by laminating and molding a laminate in which resin-impregnated glass cloth is arranged on the upper and lower surfaces of resin-impregnated paper, and metal foil is further arranged on the upper or lower surface of the resin-impregnated paper. This electrical laminate is characterized in that the weight of the resin-impregnated glass cloth on the metal foil side is greater than the glass cloth weight of the resin-impregnated glass cloth on the opposite side of the metal foil, so that it is difficult to use in normal conditions and during printed wiring board processing. This invention was able to eliminate concave warping with the metal foil side facing inside, and the present invention will be described in detail below.
